Following a trip to Alaska, Facebook CEO Mark Zuckerberg recently wrote a blog post defending — yet again — the idea of establishing a form of basic income in the U.S.

Zuckerberg said he supported Alaska’s Permanent Fund Dividend, which pools money from the state’s oil revenue and returns it to residents at the end of the year. In 2016, that dividend amounted to $1,022 per eligible resident.

He used his experience at Facebook to explain how the economics of human condition can change for the better if people are given a basic income to live off, such as the Permanent Fund Dividend in Alaska.

“Seeing how Alaska put this dividend in place reminded me of a lesson I learned early at Facebook: organizations think profoundly differently when they’re profitable than when they’re in debt,” Zuckerberg wrote. “When you’re losing money, your mentality is largely about survival. But when you’re profitable, you’re confident about your future and you look for opportunities to invest and grow further. Alaska’s economy has historically created this winning mentality, which has led to this basic income. That may be a lesson for the rest of the country as well.”
